Robot Boss

To build the Robot, you first need the Metalwork Station, which you should have been able to get after killing the Penguin UFO Boss. Once you have it, you can build the 4 robot parts, which then combine into the Inactive Robot.

If your having difficulty with the head, you first need to build the Brain Extractor. Take it down to the planet and start killing creatures with it until you get a Superior brain, which you can then build into an Artificial Brain and then finally into the Robot Head. The drop rate is pretty low on Superior Brains, so be patient.

Once you have the Inactive Robot, take it down to any planet and place it. Just like the previous boss, nothing will happen until you interact with it.

The Robot isn't much harder than the Penguin UFO Boss, but you should still be prepared. Try to be in the best armor available and have a good melee weapon, as this boss tends to stay much closer to you than the UFO did.

Before you begin the fight, put a wall up between you and the robot. Once active, you can then continue to build the wall around the robot, trapping him in place. You can then punch out sections to shoot through or melee through to hit him. This is the easiest way to fight him, as it keeps him locked in one place and unable to move.

If you choose to fight him in the open, just stay mobile and you will greatly increase your odds of surviving. Having friends around to help is always a plus, and make sure to have plenty of bandages in case you take one too many hits.

Killing the boss rewards you with the Microchip, which can be used to create the Robotic Crafting Table.
